Minneapolis may make home sellers check insulation, draftiness

Minneapolis leaders want to add new requirements for anyone who sells an old home in the city that would require drilling a hole in a wall to check the insulation and using a special fan to see if the building is airtight.

The reviews by outside evaluators would give home buyers more information on how much energy is leaking out and help meet the city’s goal of fighting climate change through a more energy-efficient housing stock. A related proposal would require landlords to disclose average energy costs to prospective renters.
